can't operate samsung allshare- please help

hope it's the right forum.
I have Samsung 51e550 plasma.
used to work with allshare until something happened to my desktop and i had to install and make settings from the beginning.
my os is win 7 64 bit.
after installing allshare , set the folders i want to share, allowed all permissions in allshare and defined sharing on those folders in windows, i can't see those folders in allshare window, even that it shows kind of files transferring proses after i opened the program for the first time.
when i try to add again one of the folders/files it says : "the folder/file is already exist".
in file management window of allshare it says on 'device list' - "no shared folder" , no device ".

the tv do show the allshare device from which i used to choose and see the shared folders/files ( so i suppose it is not an network connection issue) , but when i choose from it, let say videos, or other one's (pictures etc.), it says that there are no files/folders.
i read a lot on the net and tried almost everything, but it didn't help.
also, a lot of times when i try to click one of the allshare options, the program crashes.
please, please- HELP.

you are so right !!
allshare is the most terrible program i ever seen.( and I'm not the only one saying it).
looks like Samsung ran out of budget doing their tv (which I'm very pleased with) , and gave b (or c) grade programmers to build allshare.

my catch 22 is that i tried to install serviio (several times- also as administrator) , and it crashes during installation ( the installtion screen freeze , and windows massage " something went wrong with installing... ") .

if someone can help me with this, I'll be very grateful.

edit:
i'll try mezzmo .

looks like my problems will never end...
tried mezzmo (a trial version) .
after installing and try to operate, it gives me all the time some strange error massage : "out of memory" (i have a lot of free memory in my PC).

can someone give me a link to a approved ( some of them are false ) download a free version of one of the above ?


edit:
i gave up .
tried other version of mezzmo, other problems.
went back to allshare and suddenly , at list for now, it works fine.
